DEPA Air Operated Diaphragm Pumps, Cast Metal Pumps, Series M

DEPA Air-Operated Diaphragm Pumps were developed for the smooth transfer of abrasive, solids-containing and viscous media. The direct pneumatic drive means that there is no need for electric driven motors, base plates and couplings.
The compact and efficient designs are easy to transport, therefore, they are flexible enough to use on construction sites, in the mining industry as well as in stationary operation in different industries.

Virtually all fluids, from water to slurries/pastes, are pumped.

Bodies made of cast aluminum AL 233, ductile iron GGG 40 and cast stainless steel 316L are available so that the pumps can be individually adapted to transfer tasks. The elastomer materials for diaphragms, valve seats and valve balls have to be selected from the compatibility list. The units are manufactured in five different sizes (types), with the connections DN 15 - DN 80, which is equivalent to R ½" - R 3".

All pumps are delivered ready for operation and only have to be connected to the main air supply system.
